Abstract

Objective: To determine the association between human immunodeficiency virus (HIV) infection and status epilepticus and compare the outcomes of patients with status epilepticus with or without underlying HIV infection.

Methods: Patients with primary diagnosis of status epilepticus (cases) and status asthmaticus (controls) were identified from the 2002-2009 Nationwide Inpatient Sample (NIS) which is representative of all admissions in the United States. We performed logistic regression analysis adjusting for age, gender, co-morbid conditions, including hypertension, diabetes mellitus (DM), renal failure, alcohol use, and opportunistic infections. We compared the in hospital outcomes among patients admitted with status epilepticus in strata defined by underlying HIV infection.

Results: The rate of concurrent status epilepticus and HIV has increased over the last 7 years in hospitalized patients with status epilepticus in United States (0.14%-0.27% p<0.0001). The HIV infection was significantly associated with status epilepticus (odds ratio [OR]: 2.2; 95% confidence interval [CI]: 1.8-2.6; p<0.0001)) after adjusting for age, gender, opportunistic infections, and cardiovascular risk factors. The in-hospital mortality was significantly higher while discharge with none or minimal disability was significantly lower in status epilepticus patients with underlying HIV infection (17.5% vs. 9.9%, p<0.0001) and (50.4% vs. 63.3%, p<0.0001), respectively.

Conclusions: Our study suggests that there is a direct association between HIV infection and status epilepticus. The proportion of patients admitted with concurrent status epilepticus and HIV infections is increasing and such patients have higher rates of poor discharge outcomes.

Keywords: human immunodeficiency viral infection; seizures; status epilepticus.
